The HESI is a Class 3 Igniter used for direct spark ignition of oil or gas igniters, small burners, and combustion turbines. Forney’s High Energy Spark Igniter (HESI) provides a highly reliable, non-fouling source of ignition for oil or gas igniters or small burners. The Forney horn igniter is designed to be a direct replacement for the OEM igniter on tangentially fired boilers. This igniter features improvements such as the. The MAXFire® Series gas igniter incorporates the “protected primary combustion zone” design in each of the 5 capacities available. MAXFire® gas igniters provide the most reliable source of energy for main flame ignition, flame stabilization, and boiler warm-up.

The Forney horn igniter is designed to be a direct replacement for the OEM igniter on tangentially fired boilers. Pre-packaged, pre-engineered product minimizes cost and lead time.
Th e power unit develops 12 joules of energy delivered to the spark tip through the use of fornsy duty electrical components.
Stainless steel with a silicon carbide insulator Maximum Tip Temperature: As a gas igniter, the gas is directed to the tip through the single flexible tube.
Combustion air is provided from the windbox. A factory mounted NEMA-4 junction box with all on-board electrical devices pre-wired to terminals is a standard feature which reduces installation time.
Forney Ignition & Combustion HESI Igniters – Forney Corporation
The spark rod is available in the standard rigid design or in a flexible configuration for use in a tilting tangential burner application.
Other changes implemented included checking air flow on scanner fans, verifying the time sequence on oil valves, and performing bi-weekly preventive maintenance on the igniters.
An ATEX version is also available. Application Flexibility The protected primary combustion zone ensures reliable operation in multiple environments. Surface gap Spark Tip Material: The mount tube is typically welded to the burner front plate, and the igniter guide tube slides into the ignkter tube and is secured in place by a split clamping ring and packing gland assembly.
Return to top of page. It was also identified that the ceramic insulators in many of the tips were broken or had cracks from being dropped on the burner forny during maintenance, and this caused malfunctions in the spark tips which required replacement.
The Q87 igniter is the best choice when dual fuel natural gas and No. Product Overview Product Overview The Q is a self-contained Class 1 oil or gas igniter used for burner ignition, stabilization or boiler warm-up. It is also the choice when both air and steam atomization is required for No. Most applications require no igniter retraction reducing installation costs and ongoing maintenance. The HESI produces a consistent spark due to its foul resistant design, while the optical detector proves flame without physical contact.
Application Flexibility The protected primary combustion zone ensures reliable operation in multiple environments. The HESI produces a powerful joule spark approximately three times per second at the primary combustion zone. The dual fuel horn igniter fires either oil or gas without a change of equipment, allowing for a quick and effortless change over of fuel.
Igniters provide the ignition energy to ignite the main fuel for utility and large industrial steam generators. Return to top of page. This controlled mixture of fuel and air in the primary combustion zone results in a highly reliable, stable igniter flame.
Atomization takes place at the rear of the igniter away from the heat of the tip resulting in no fouling or need for cleaning. High Efficiency Air Atomizer The internal mix atomizer is selected from a standard set of sizes for each project. Durability Heavy duty material and no moving parts to wear out. Optional Flame DetectiOn The flame detector senses flame inside the horn and discriminates from flames outside the horn.
The ignition process starts inside the guide tube away from the burner environment resulting in an extremely stable and reliable igniter. Horn Igniter The Forney horn igniter is designed to be a direct replacement for the OEM igniter on tangentially fired boilers.
The HESI produces a consistent spark due to its foul resistant design, while the optical detector proves flame without physical contact. As a result this igniter is self-stabilized, highly reliable and requires virtually no maintenance. Since the etector is mounted to the igniter windbox, it does not require cooling air. Return to top of page. Both rigid and flexible spark rods can be provided with an optional retraction assembly to allow the spark tip to be inserted and retracted from the firing position.
These three features combine to produce a highly reliable igniter. Product Overview Product Overview The Forney horn igniter is used on tangentially fired boilers for forey ignition and warm up, typically as a Class 2 igniter.
Flexible Single Tube igniters. The HESI spark tip is a nonfouling, surface-gap tip which is replaceable as a unit by a threaded connection.
